Cooking indicator defective ?! Caution WMF service poor

Unfortunately, there is a problem with the "cooking signal", it stuck to the parboiling gasping for some time directly to the first ring, which may not be and can be a security problem, because that occurs sporadically.

Unfortunately WMF is to express using the contact form and e-mail only after the 4th contact able to be binding. The question of a security problem or defect is not answered. The cover should only be eingschickt, without simultaneous replacement with new goods.

So poor quality and service you can not expect from WMF. The replacement appears to be okay, maybe I will buy in the future rather then from another manufacturer. The pricing policy shows traces - I am disappointed!
